hello's! i've recently installed freebsd 5.4 and patched up to p6. since the install and up to this patch level, i'm not certain the second cpu (hyperthreading, not physical cpu) is being used. i guess it could just be top not showing it, cuz it's in my kernel and in dmesg. relevant kernel lines are: options SCHED_4BSD options SMP device apic and relevant dmesg output is: CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2795.24-MHz 686-class CPU) Hyperthreading: 2 logical CPUs FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu0: <ACPI CPU> on acpi0 cpu1: <ACPI CPU> on acpi0 SMP: AP CPU #1 Launched! when using top, i always see CPU0, and the column under 'C' is always 0. is there another tool i can use to see cpu scheduling or am i missing something obvious (or obscure)? for the record, i've tried more than one cpu, and freebsd 5.2.1 was able to see and use two cpu's with the same hardware. insight appreciated! joe
